DuPont claims a temperature range of about 450 degrees F as do the other
manufacturers of polytetraflouoethylene (PTFE) aka Teflon (tm), except for
W.L. Gore who claims 600 degrees F with their industrial line of PTFE
products. Most literature also warns of the toxic gas emitted by PTFE at
temps above 500 degrees..... be careful...
